Improvement in hay and cotton presses



UNITED STATES PATENT OFFICE.

HENRY BARNES, OE BLAIRSYILLE, ASSIGNOR TO HIMSELF AND N. G. MAORUM, OF PITTSBURG, PENNSYLVANIA.

IMPROVEMENT IN HAY AND COTTON PRESSES.

Specification forming part of Letters Iatent No. 22,216, dated November 130, 1858.

To all whom it may concern.:

Be it known that I, HENRY BARNES, of Blairsville, in the county of Indiana and State of Pennsylvania, have invented anew and Improved Press for Oompressing Hay, Cotton, and other Substances that are Compressed for' Baling; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the an nexed drawings, making a part of this speciiication, in which- Figure l is a longitudinal vertical section of my invention, taken in the line x w, Eig. 2. Fig. 2 is a horizontal section of the same, taken in the line y y, Eig. l.

Similar letters of reference indicate corresponding parts in the two figures.

To enable those skilled in the art'to fully understand and construct my invention, Iwill proceed to describe it.

A represents an oblong rectangular pressbox, constructed within a strong framing, B, and provided as usual with the necessary doors, a. The press-box may be placed either in a vertical or horizontal position. The drawings show the latter position, the framing being mounted on wheels for the convenience of transporting the press, or moving it with facility from place to place.

C represents a follower,which is fitted within the box A, and has a rod, D, attached to it, said rod resting on a friction-roller, b, placed in the framing B. In or to the upper surface o1" the rod D a rack, E, is attached, and in the framing B, just above the rack E, a cam or eccentric, E, is fitted or placed. This cam or eccentric is of scroll form, as shown clearly in Fig. 1, and it is toothed and gears into the rack E.

By referring to Fig. l itwill be seen that the rack E is in an inclined position, so as to compensate for the varying diameter of the cam or eccentric E. This rack Inay be perfectly straight and placed in an inclined position, or it may be slightly curved, according to the form of the cam or eccentric. If the latter is oI" a perfectly regular scroll form, a straight inclined rack would be requisite.

If, however, it differs from said form, the rack would be necessarily of curved form, or curved, straight, and zigzag form, corresponding to the varying distances of the points oi' the periphery of the cam or eccentric from its axes. The under side of the follower-rod D may also be curved, as shown at c, to favor the irregular shape of the cam or eccentric; but I prefer to have the rack E perform the work alone, as in the latter case the follower-rod is allowed to work horizontally. The cam or eccentric and the rack E are of course constructed of metal, the other parts being of wood. The power may be applied directly to the axis of the cam or' eccentric, or through the medium of gearing c, as occasion Inay require. v

The operation. will readily be seen. When the cam or eccentric is turned in the direction of arrow 1, so as .to shove the follower O inward, the speed of the follower will be gradually decreased as the periphery of the cam or eccentric gradually approaches nearer its axis. The leverage and power therefore will be correspondingly increased as power is required.

This invention is extremely simple and efiicient, may be constructed at a small cost, and

.there are no parts liable to get out of r repair.

I ain aware that eccentric pulleys attached to a movable axis have been used for obtaining a progressive power; but I am not aware that a geared cam or eccentric placed on a stationary axis and used in connection with a rack attached to the follower-rod has been employed for such purpose. I do not claim therefore, broadly, the employment or useof an eccentric or cam for the purpose set forth 5 but I do claim as new and desire to secure by Letters Patent- The arrangement and combination of the geared eccentric F, inclined rack E, and follower-rod D, substantially as and for the purpose herein shown and described.

HENRY BARNES.
